Certain dusts, such as oak or beech dust, are considered
as carcinogenic, especially in connection with wood-treat-
ment additives (chromate, wood preservative). Materials
containing asbestos may only be worked by specialists.
– As far as possible, use a dust extraction system suitable
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the
materials to be worked.
Prevent dust accumulation at the workplace. Dusts can
easily ignite.
Integrated Dust Extraction with Dust Box
(see Fig. A1 – A4)
Attach the dust box 2 onto the extraction outlet 7 until it
latches.
To empty the dust box 2, press the latching levers 3 on the
side of the dust box ( ). Pull off the dust box toward the bot-
tom ( ).
Before opening the dust box 2, it is recommended to loosen
the dust from the filter element by gently striking it against a
firm support (as shown in the figure).
Grasp the dust box 2 by the recessed grip, fold the filter ele-
ment 8 upward and empty the dust box. Clean the thin plates
of the filter element 8 with a soft brush.
External Dust Extraction (see figure B)
Slide the extraction adapter 9 onto the outlet piece 7. Ensure
that the latching levers of the extraction adapter engage. The
extraction adapter 9 accepts a vacuum hose with a diameter
of 19 mm.
Connect the vacuum hose 10 to a vacuum cleaner (accesso-
ry). An overview for connecting to various vacuum cleaners
can be found at the end of this manual.
For removal of the extraction adapter 9, press the latching le-
vers together at the rear and pull the extraction adapter off.
The vacuum cleaner must be suitable for the material being
worked.
When vacuuming dry dust that is especially detrimental to
health or carcinogenic, use a special vacuum cleaner.
Replacing the Sanding Sheet (see figure C)
When attaching a new sanding sheet, remove any dust or de-
bris from the sanding plate 5 (e. g. with a brush).
To ensure optimum dust extraction, pay attention that the
punched holes in the sanding sheet match with the holes in
the sanding plate.
The sanding plate 5 is fitted with Velcro backing for quick and
easy fastening of sanding sheets with Velcro adhesion.
Before attaching the sanding sheet 4, free the Velcro backing
of the sanding plate 5 from any debris by tapping against it in
order to enable optimum adhesion.
The machine is fitted with 2 sanding sheets that can be
changed individually, depending on the degree of wear.
Only use the machine when both sanding sheets are
mounted.
Only use sanding sheets with the same grain size.

Position the sanding sheet 4 flush alongside one edge of the
sanding plate 5, then lay the sanding sheet onto the sanding
plate and press firmly.
To remove the sanding sheet 4, grasp it at one of the tips and
pull it off from the sanding plate 5.
Sanding sheets of the Bosch Delta Sander can be used.
Sanding accessories, such as fleece pads/polishing cloth
pads, are attached to the sanding plate in the same manner.
Selecting the Sanding Sheet
Depending on the material to be worked and the required rate
of material removal, different sanding sheets are available:
For the working of all wooden
materials
For coarse-sanding, e. g. of rough,
unplaned beams and boards
For face sanding and planing small
irregularities
For finish and fine sanding of hard
woods
For the working of paint/enamel
coats or primers and fillers
For sanding off paint
For sanding primer
For final sanding of primers before
coating
For reworking or polishing, especially of metal and stone, use
fleece/polishing cloth pad.
Depending on the desired surface quality of the workpiece,
different fleece types or polishing cloth pads are to be used.
Replacing the Sanding Plate (see figure D)
Slide the SDS button for release of the sanding plate 6 all
the way to the right.
Remove the sanding plate 5.
Guide the sanding plate 5 from below against the sand-
ing plate holder and firmly press them together.
Slide the SDS button for release of the sanding plate 6 all
the way to the left.
If, e. g., the front tip of the sanding sheet is worn, you can also
remove the complete sanding plate and reattach it turned by
120°.
Specialty Sanding Plates
You can replace the supplied sanding plate 5 with a specialty
sanding plate, which is available as an accessory.
The specialty sanding plate is attached in the same manner as
the one supplied.
Attach and remove the respective sanding sheets in the same
manner as when changing original sanding sheets.
